Your activated locations are listed here. You can switch to another location by clicking on the name, or compare data with the current location by checking the box.

This graph allows a quick look over the data that can be downloaded. Long data series are dynamically aggregated to daily or monthly values. It automatically refreshes on changes.

You can zoom by click and drag to left or right. A click on a weather variable name in the legend below the chart hides the data series for better readability.

Weather variables information

Pressure: Atmospheric air pressure reduced to mean sea level as most commonly used for weather reports. The local pressure varies with altitude. Locations at higher elevation have a lower local atmospheric pressure.

Precipitation amount: Total precipitation amount including rain, convective precipitation and snow. 1mm at 10:00 is comparable to a rain-gauge measurement from 9:00-10:00.

Snowfall amount: Fraction of total precipitation that falls down as snow and is converted to cm instead of mm.

Total cloud cover: Percentage of the sky that is covered with clouds: 50% means half of the sky is covered. 0-25% clear sky, 25-50% partly cloudy, 50-85% mostly cloudy and above 85% overcast.

Low, mid and high cloud cover: Cloud cover at different altitudes. High clouds (8-15 km) like cirrus are less significant for total cloud cover than low (below 4 km) like stratus, cumulus and fog or mid clouds (4-8 km) like alto cumulus and alto stratus.

Solar radiation: Global radiation (diffuse and direct) on a horizontal plane given in Watt per square meter.
